Title: Network transaction method, method and system for data processing, terminal equipment, and information storage medium
Inventor: YOKOTA TAKASHI
IPC: G06Q50/00
Filed: 2000-04-17
Abstract: PROBLEM TO BE SOLVED: To realize extensive trade of invention property rights like patent rights and intellectual property like inventions which have not been applied for patents. SOLUTION: A desire to purchase an invention property right or intellectual property is presented as data in a home page of the Internet in a general perusal state, and a dealer accesses a retrieval server 15 of the Patent Office 14 to confirm that an invention property right and a seller are appropriate when the dealer will purchase the invention property right from the seller. In the case that the dealer has purchased intellectual property, the dealer applies for a register to the Patent Office 14 to obtain an invention property right, and the dealer presents the purchased invention property right to a buyer as data and takes charge of procedures of transfer to the Patent Office 14 accompanying trade in the invention property right.  Thus trade of invention property rights and intellectual property is extensively invited, and trade in invention property rights and intellectual property is easily promoted because it is unnecessary for sellers and buyers to perform the complicated work like applications for registers or transfer procedures.

Title: Inverter device and dc input method
Inventor: YASUNO YOSHIO
IPC: H02M7/5387
Filed: 2000-04-18
Abstract: PROBLEM TO BE SOLVED: To regenerate power when DC is inputted. SOLUTION: In the inverter device for both AC/DC that has a rectification circuit 11, a smoothing capacitor C, and an inverter 20 for outputting the voltage of the smoothing capacitor to AC for outputting to a motor M, and allows DC input DC to be located between the AC input terminal of the rectification circuit and a negative voltage output terminal, an input terminal R of the rectification circuit is connected to a positive voltage output terminal 14 by a lead wire 21 when inputting DC, and at the same time an AC input terminal T is connected to an output terminal 16 of a switch 13 by a lead wire 22. The DC input supplies DC to the smoothing capacitor and the inverter via the lead wire 21 and a thyristor switch.  In damping operation, the generation power of a motor passes through the inverter, the lead wire 22, the diode 6, and the lead wire 21 and is regenerated at the side of the DC input DC. AC is inputted by avoiding the lead wires 21 and 22. When AC is to be inputted, the generation power of the motor is not regenerated at the AC side.

Filed: 2000-04-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical switching device which is simple in structure, small and light, and permits a high speed response, and to provide a switching device using the same. SOLUTION: An optical extraction part 17a is brought into close contact with an upper substrate 11 electrostatic attractive force between a transparent electrode of the optical extraction part 17a and a transparent substrate of the upper substrate 11. When light P1 is made incident vertically to a V-shape groove 11a of the upper substrate 11, the light P1 is made incident to the optical extraction part 17a from the upper substrate 11, and made to exit from the back face (tapered part 20a), and then passes through the lower substrate 21 to become transmission light P2. The light extraction part 17a is attracted to the side of the lower substrate 21 by the electrostatic attractive force between the transparent electrode on the lower substrate 21 and the transparent electrode on the light extraction part 17a.  In this state, the incident light P1 is totally reflected by a total reflection plane 11A, and this reflected light P3 is made to exit from the V-shape groove 11b. Thus, the incident light P1 can be taken out as the transmission light P2 or the totally reflected light P3 switched in-between.

Filed: 2000-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a sphygmomanometer with which influence of stasis on measuring blood pressure is gauged and errors caused by stasis in sphygmomanometry is prevented. SOLUTION: A sphygmomanometer is provided with a sensor for venous pressure, which detects venous pressure at a peripheral part rather than a part where a cuff is attached. After increasing pressure of the external pressure of the cuff (ST1-ST3), cuff pressure, Korotokoff sound, and venous pressure are measured (ST5) during the process (ST4-ST6) of slowly reducing the external pressure of the cuff. Systolic blood pressure and diastolic blood pressure are found from cuff pressure at the beginning and the end of Korotokoff sound tentatively (ST7), and the maximum value of peripheral venous pressure at the time of measuring blood pressure is computed (ST8). Whether the difference between diastolic blood pressure and the peripheral venous pressure is less than the value, which has been set up, is determined (ST9).  If the difference is determined to be less than the value, which has been set up, the manometer informs to measure blood pressure again.
